As far as U.S. Subaru dealers go, yes, the only wheels they offer that will fit over the STI Brembos are the STI BBS wheels.

Why do you want Subaru OEM wheels? There are a LOT of choices in the aftermarket.

i like staying with factory exterior stuff... i would get other wheels that would fit over the brakes but the BBS RK's dont... and volk ce28ns are madd loot. I was thinking of just modding the R160 rear to work with the 6 spd but i figure its just gonna break...
